Can you repackage the binary as a data-only kld, with a couple of public
symbols wrapping the beginning and end of the binary, or a couple of
symbols with start and length? You could then have the loader pre-
load the .ko at boot time.
The only other way is to wait until the system is up and load the code
into your driver through an ioctl.
